Don't consider this a blocker, but it'd be nice to have a test to verify that in case of any exception thrown we do actually perform the unlock.

This is a really hard one because it requires that we've already acquired the lock, but then something happened (timeout?) and the the lock state changed. I'd have to think though how we could replicate that scenario.

This PR adds locking to the hive commit path for tables. The current commit path is unsafe as competing updates may overwrite other clients that are using locking.
This implementation is the most restrictive in that it will fail a commit if it cannot immediately acquire a lock.
